Knowledge of Good and Evil?

[Sheila]

Just what exactly is THE knowledge of good and evil? I know that it's the ability to tell the difference. We wouldn't have had the difference without the rules (commandments) What I'm asking is--what is the knowledge? Was it that we have the ability to lie? In the garden of Eden we would only have known good and the truth. How did we know what was evil until God gave us the rules and told us what evil was? The only evil that we would have been aware of was that we were to be obedient to God. The was the only rule. When we ate of the tree of knowledge, what was the knowledge we gained? Did we learn that not only can we make our own decisions but we can lie--God cannot lie, he can only tell the truth.
When we were in the garden of Eden and God walked among us--was this heaven? Did we get ejected from heaven? Are we fallen angels? Is this why the devil thinks he has a right to us? Are we the fallen angels--the one-third of heaven that fell? Did God wipe our memories and then remake us into something less than the angels we were?
